# Before
This is hard to read:
```
if (ca.AttributeType.FullName == typeof(Mirror.CommandAttribute).FullName) {
...
}
```
# After
```
if (ca.AttributeType.Is<Mirror.CommandAttribute>()) {
...
}
```
# Before
WeaverTypes declared a static variable like this:
```cs
public static TypeReference int32Type;
```
Weavertypes then loaded the variable in SetupTargetTypes like this:
```cs
int32Type = ImportSystemModuleType(currentAssembly, systemModule, "System.Int32");
```
Note we lookup the type with a string, any typo there won't be detected until the code is executed. It will also not be found by the IDE when you click "find references", or when you refactor.
Then we use it like this:
```cs
var intType = WeaverTypes.int32Type;
```
This is a DRY violation: I have to modify 3 different code sections just to say that I want the int32 type.
# After
Get rid of all the duplication, and use the type instead of a string:
```cs
var intType = WeaverTypes.Import<int>();
```
No need for static variable, or to add it in SetupTargetTypes.
* fixing null ref error when local player is destroyed
* removing null objects
* fixing InvalidOperationException
* moving code to its own function
* Update Assets/Mirror/Runtime/ClientScene.cs
* Update ClientScene.cs
Improving logging
- making sure sceneId is always hex
- only logging "Client spawn for ..." if it was successful
* Update ClientSceneTests_OnSpawn.cs
- Adding handlers in Awake instead of Start to make sure they are added before start on headless
- using GetComponent for NetworkManagerListServer
- Adding asserts to make sure values are set
